OK here is my 2 cents, bought a 23.5 used about 7 years ago on Audiogon for $2500 I would rather live on the streets before selling it, this amplifier was used for many hours every day always gave me chills. I had it in storage for 2 years due to losing my job I had to relocate to another state for employment. After 2 years in storage I set up my audio gear few weeks latter I got the pop from the left speaker comes and goes (I wonder if this is due to not using the gear for such a long time) so I took my amplifier to Technetron in NYC an authorized Levinson repair shop. All the smaller silver capacitors were replaced and some soldering was done due to age of the system. I spoke with Pyramid and Technetron about this repair before I decided where to go, I was initially going to ship to Pyramid due to their reputation but shipping would have cost me hundreds of dollars so I went local. Let me state, Pyramid and Technetron both told me the big capacitors do not need to be replaced on the 23.5 they last forever, I told them I was willing to pay for the replacement but they insisted I was waisting money, this is coming from technicians that have over 15 years experience repairing Levinson gear, I was surprise cause I would have no problems giving them the money to replace the large capacitors. I am about to go pick up my amplifier in a few hours. I was told after the repair I should get 15 more years of joy with the 23.5 before I would need another repair I was told by the technician that the older Levinson were much better than the newer ones, they were hand made. He told me due to age and heat the boards in the amplifier turned brown he told me not to leave the amplifier on when I was not using it he said some people leave the amp on 24/7, my amplifier was on all day and only turned off before bed. A new amplifier at this level would cost over $12000 I highly doubt you get better sound than the older Levinson.
